1.jsp代码：

<%--
    Document   : application
    Created on : 2009-10-4, 13:18:53
    Author     : lucifer
--%>

<%@page contentType="text/html" pageEncoding="UTF-8"%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"
"http://www.w3.org/TR/html4/loose.dtd">

<html>
    <head>
        <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
        <title>JSP Page</title>
    </head>
    <body>
        get Server Info:
        <%=application.getServerInfo()%>
        <br>
        get Context Path:
        <%=application.getContextPath()%>
        <br>
        get Real Path:
        <%=application.getRealPath("/Application.jsp")%>
        <br>
    </body>
</html>

get Server Info: Apache Tomcat/6.0.18
get Context Path: /TestMethod
get Real Path: D:/PRogram Files/NetBeans 6.7.1/www/TestMethod/build/web/Application.jsp
